Free Referring Domain Extractor
Turn a messy list of backlink URLs into a clean list of unique referring domains. Paste your links and instantly get the deduplicated domains — grouped by root domain or full host, counted, sortable, and exportable to CSV. Free, no sign-up, runs in your browser.
What this tool does
Backlink exports often contain thousands of URLs from the same handful of sites. What actually matters in a backlink profile is the number of unique referring domains, not raw link count. This tool collapses your URL list into unique domains, tells you how many links come from each, and gives you a tidy list you can copy, sort, or download.
How to use it
It is instant:
- Paste your backlink URLs, one per line.
- Choose root domain or full host grouping.
- Sort by link count or alphabetically.
- Copy the domains or export a CSV.
Root domain vs full host
Grouping by <strong>root domain</strong> treats <code>blog.example.com</code> and <code>example.com</code> as the same site, which is how referring-domain counts usually work. Grouping by <strong>full host</strong> keeps subdomains separate, which is useful when you want to see exactly which subdomains link to you. The tool handles common two-part TLDs like <code>.co.uk</code> so the root domain is detected correctly.
Why referring domains matter more than links
One site linking to you a hundred times is far less valuable than a hundred different sites linking once. Search engines largely count the diversity of referring domains, not the total number of links, so measuring unique domains gives a truer picture of your link profile's strength. This tool makes that number easy to see and track over time.
Common uses
Use it to deduplicate a Search Console or backlink export, to count your true referring-domain total, to prepare a clean domain list for a disavow review, or to feed domains into other audit tools. Pair it with our Toxic Backlink Checker to score the extracted domains, or the Backlink Type Classifier to categorise them.
Privacy
The extraction runs entirely in your browser — your URL list is never uploaded, logged, or stored. You can process private backlink exports without any data leaving your device.
